This is due to an ongoing labour dispute between the B.C. Teachers Federation and the B.C. government, and the Prince Rupert School District director banned it before googling where the quote came from. If he had, he might have also see that Dr. Seuss intended Yertle's takeover of the pond and surrounding areas as an analogy for the Nazi invasion of Europe. In other words, this hapless bureaucrat has unwittingly aligned the B.C. government with Hitler. D'oh!

But to be fair, Yertle the Turtle can also be read as a prescient rebuke of income disparity that hits particularly close to home in our Occupy era. As can its polar opposite, Thomas the Tank Engine, which is totally in the tank for the one per cent.

My two-year-old had a bad cough not so long ago and we spent a lot of time on the fictional Island of Sodor -- reading books, watching Netflix and playing iPad apps based on The Railway Series by the late Rev. Wilbert Awdry, an Oxford-educated Anglican son of a vicar who grew up near The Great Western Railway.

The series' socio-economic subtext rose to the surface while reading Day of the Diesels, based on a 2011 Thomas and Friends TV movie. Awdry's kiddie-culture empire, begun back in 1945, has always been fuelled by Britain's oft-criticized class system, as it romanticized the posh steam engines while demonizing the new blue-collar diesel engines.

But this new Thomas tale took that even further with a surprisingly prescient occupation of the Steamworks by the lower-class Diesels.

"Steamies don't go to the Dieselworks," spat Thomas, with shocking venom for a kids' book. "It's dark and dirty, and Diesels can be devious." This class division is encouraged by rotund railway boss Sir Topham Hatt, an aristocratic industrialist in top hat and tails. Also known as the Fat Controller, he rules the rails with an iron fist and plays Steamies and Diesels against each other to ensure no one questions his authority.

Thomas' best friend Percy is portrayed as naïve for thinking, "It wasn't fair that they should live in a dirty, dingy place" and for staying overnight at the Dieselworks, something no steam engine had ever done before. Naturally, when the uprising begins with the Diesels taking over the Steamworks, they're portrayed as evil despite their legitimate claims. And when Sir Topham Hatt arrives, he plays the typical politico, saying he always planned to build a new Dieselworks, but "everything takes time. And everyone must wait their turn." Yep, in Sodor they practice trickle-down economics, and the Diesels are at the bottom.

The award-winning book Click, Clack, Moo: Cows That Type tells the story of a bovine labour dispute. Finding a typewriter, the cows post a demand on the barn door: "Dear Farmer Brown, The barn is very cold at night. We'd like some electric blankets. Sincerely, The Cows." Ignored, the animals go on strike until a neutral third-party (the duck) negotiates a deal.

It's a cute story that sees the workers get some concessions without actually upending the power structure, unlike Yertle the Turtle, the most 99 per cent-friendly children's story of all time.

Dr. Seuss opposed consumerism (How the Grinch Stole Christmas) and discrimination (Horton Hears a Who) while promoting an environmental agenda (The Lorax), but he delves deepest into politics with Yertle. I read it a lot initially because Seuss' poetic dedication to anapestic tetrameter makes his writing the most enjoyable to read aloud.

But when the Occupy movement kicked off last fall, it took on a deeper meeting.

Yertle is the king of the pond, but initially "the turtles had everything turtles might need. / And they were all happy. Quite happy indeed." Then Yertle got greedy. As he was "the ruler of all [he] can see," Yertle decided he needed to see further, so he commanded his turtle subjects to stack themselves into a throne that would lift him higher. Eventually hundreds of turtles obeyed, moving him ever upward. But at the bottom was a plain little turtle name Mack. "Your majesty please, I don't like to complain / But down here below, we are feeling great pain. / I know, up on top you are seeing great sights, / But down here at the bottom we, too, should have rights."

In that now-controversial quote, Seuss was warning against Hitler-esque avarice, but also that increasing the gap between the powerful and powerless -- the haves and have-nots, if you will -- would lead to disaster. Eventually, this rather literal pyramid scheme collapses, leaving Yertle the king of the mud while the "turtles, of course... all the turtles are free / As turtles, and maybe, all creatures should be."

Now, my son is a toddler, and he just likes trains and turtles. But even if the political underpinnings of the Yertle and Thomas books are way over his head -- not hard, as he's only about three feet tall -- they still impart moral lessons. One reinforces class divisions and imperiousness while the other promotes equality and compassion.

But apparently equality and compassion aren't appropriate for B.C. classrooms.
